NAME
       XInstallColormap, XUninstallColormap, XListInstalledColormaps -
       control colormaps

SYNTAX
       XInstallColormap(display, colormap)
             Display *display;
             Colormap colormap;

       XUninstallColormap(display, colormap)
             Display *display;
             Colormap colormap;

       Colormap *XListInstalledColormaps(display, w, num_return)
             Display *display;
             Window w;
             int *num_return;

ARGUMENTS
       colormap  Specifies the colormap.

       display   Specifies the connection to the X server.

       num_return
                 Returns the number of currently installed colormaps.

       w         Specifies the window that determines the screen.

DESCRIPTION
       The XInstallColormap function installs the specified colormap for its
       associated screen.  All windows associated with this colormap
       immediately display with true colors.  You associated the windows
       with this colormap when you created them by calling XCreateWindow,
       XCreateSimpleWindow, XChangeWindowAttributes, or XSetWindowColormap.

       If the specified colormap is not already an installed colormap, the X
       server generates a ColormapNotify event on each window that has that
       colormap.  In addition, for every other colormap that is installed as
       a result of a call to XInstallColormap, the X server generates a
       ColormapNotify event on each window that has that colormap.

       XInstallColormap can generate a BadColor error.

       The XUninstallColormap function removes the specified colormap from
       the required list for its screen.  As a result, the specified
       colormap might be uninstalled, and the X server might implicitly
       install or uninstall additional colormaps.  Which colormaps get
       installed or uninstalled is server-dependent except that the required
       list must remain installed.

       If the specified colormap becomes uninstalled, the X server generates
       a ColormapNotify event on each window that has that colormap.  In
       addition, for every other colormap that is installed or uninstalled
       as a result of a call to XUninstallColormap, the X server generates a

       ColormapNotify event on each window that has that colormap.

       XUninstallColormap can generate a BadColor error.

       The XListInstalledColormaps function returns a list of the currently
       installed colormaps for the screen of the specified window.  The
       order of the colormaps in the list is not significant and is no
       explicit indication of the required list.  When the allocated list is
       no longer needed, free it by using XFree.

       XListInstalledColormaps can generate a BadWindow error.

DIAGNOSTICS
       BadColor  A value for a Colormap argument does not name a defined
                 Colormap.

       BadWindow A value for a Window argument does not name a defined
                 Window.
